Misae reluctantly allows Shin to use a tricycle, but panic ensues when he drops it into a dirty lake. While she searches, Shin wanders off, causing Misae to worry about her parenting until she realizes he left to watch Action Mask. Separately, Shin suffers from constipation after not using the toilet for three days, requiring medicine from his teachers to recover. Later, Hiroshi takes Shin to a restaurant because Misae is absent. Hiroshi finds the outing tedious and feels significant relief when Misae finally returns home.
